Basically Ace Attorney set in the shogun era, with similar gameplay and some similarities to the story. The story is surprisingly well-written and the characters are likeable. The court trials are just okay. Overall, I recommend this game if you liked the story in Ace Attorney. Maybe pass if you're only interested in the court trials.

There's an optional R18+ patch available outside of Steam for additional character-focused routes after the main game. I did not play it, so no comment there. As an alternative, there are some YouTube playthroughs of these extra routes with the 18+ content cut out. The main game itself is fairly light in terms of sexual content, with some fanservice and a slightly icky scene in the last chapter.

The court trials (my favorite part about Ace Attorney games) were a bit disappointing. There are some leaps of logic in the arguments, and it often felt like the trials were resolved with the perpetrator confessing, rather than with clear proof. Granted, considering the setting of the game, you're not going to have evidence like photographs, video footage, and fingerprint analysis. There were also times where the game isn't clear about what evidence you need to present. But there's no penalty for wrong answers, aside from missing out on a perfect trial score.
